I was in a tree stand facing south about 15 yard into a timber with a cornfield on my left and deep timber to my right. Went out around 3:30 but didn't really see anything all day. Finally, about 5 min before the end of the day, I heard some walking off to my right. It was very dark and difficult to tell what I was seeing. Out from behind a bush this deer walks and all I could really see was his silhouette. When he walked behind the next tree I stood up and turned around, a few times he would stop to listen to me; I would stop moving as well. Finally I got pulled back and could just make out where he was. I put my dim but visible green pin on him and pulled the trigger. He ran about 40 yards and crashed.
